Hi all,
I'm designing a TSM solution for our enterprise data centre. The EDC consists
of two physical datacentres with appropriate smarts to make them appear as one
big logical entity from both the SAN and LAN perspective
We currently run a single TSM server on AIX which backs up a portion of the
application nodes in the EDC.
We don't currently have any apps that can automatically fail over, but we will
have some real soon. The reason for the TSM redesign is that we are going to
put TSM in many places around the state, and that includes backing up all of
the enterprise datacentre rather than just the odd bits that we do now. The
rest of the state will be running on windows, so we are keen to use windows in
the EDC also. The configuration manager will also run in the EDC.
Is anyone running TSM server as an application in a geographically spread
active/active windows cluster? Did you have any issues getting this to work?
Is it reliable both in normal operation and in failover?
I have the option of a p690 AIX/Veritas cluster solution or Sun F15K/Veritas
cluster, but both of those seem unreasonably expensive, and will move away from
a Windows standard approach state wide. Any insight will be helpful.
Thanks
Steve.
